Huntkey Balance King 5000 500 W Power Supply Review
Power Distribution
Contents
In Figure 16, you can see the power supply label containing all the power specs.
Figure 16: Power supply label.
If you pay attention on this label, Huntkey is saying that this unit is labeled at 25° C and presents a de-rating factor of 1.2 W per Celsius degree, which translates to 470 W at 50° C. Finally Huntkey is doing something to end up with their dishonest labeling methods.
This
power supply has four +12 V virtual rails. The monitoring circuit seems to support over current protection (OCP), as we could clearly see four “shunts” (current sensors) on the printed circuit board (Figure 17), a clear indication that this feature was present.
Figure 17: Current sensors for the four +12 V rails.
The rails are distributed like this:
- +12V1 (yellow/green wire): One of the video card power cables.
- +12V2 (yellow/black wire): ATX12V/EPS12V cable.
- +12V3 (solid yellow wire): Main motherboard, SATA and peripheral cables.
- +12V4 (yellow/green wire): The other video card power cable.
Notice that the two video card power cables use wires with the same color but are installed on different rails.
This distribution is perfect, as it put the CPU and the video cards on separated rails.
Now let’s see if this power supply can really deliver 500 W.
